To identify the complete predicate, complete subject, simple predicate, and simple subject in a sentence, we need to understand the basic structure of a sentence.

A sentence is composed of two main parts: the subject and the predicate.

The subject is the person, thing, or idea that the sentence is about. It tells us who or what is performing the action or being described in the sentence.

The predicate is the part of the sentence that contains the verb and provides information about the subject. It tells us what the subject is doing or what is happening to the subject.

Let's analyze the sentences you provided to find the complete predicate, complete subject, simple predicate, and simple subject.

19. Most readers will wait patiently for the next book in the series to be released.

- Complete predicate: will wait patiently for the next book in the series to be released.
- Complete subject: Most readers.
- Simple predicate: will wait.
- Simple subject: readers.

20. After that, we can get some popcorn at the snack bar.

- Complete predicate: can get some popcorn at the snack bar.
- Complete subject: we.
- Simple predicate: can get.
- Simple subject: we.

22. Take out the trash before it overflows into the driveway!

- Complete predicate: Take out the trash before it overflows into the driveway and makes a mess.
- Complete subject: You.
- Simple predicate: Take out.
- Simple subject: You.

The correct answer for sentence 22 is "This is a complete sentence. No correction is necessary" since it is not asking for the identification of the complete predicate, complete subject, simple predicate, or simple subject.
